Rat Terrier

The Rat Terrier originated in the United States in the early 20th century. Developed from a mix of terrier breeds such as the Smooth Fox Terrier, Manchester Terrier, and Bull Terrier, along with Beagle and Whippet influences, the Rat Terrier was prized for its ability to eliminate rats and other vermin on farms. Known for their speed, tenacity, and intelligence, these dogs quickly became popular farm companions. The breed was recognized by the American Kennel Club in 2013.
